Navigating the concepts of grammar involves understanding the nuances between active and passive voice—a crucial aspect of effective communication. The choice between these voices can significantly impact the clarity and emphasis of a sentence. In this exploration, we'll unravel the difference between active and passive voice, delve into the rules guiding their usage across various categories, and illuminate these concepts with illustrative examples. 

Distinguishing Active and Passive Voice

The verb voice indicates whether the subject of a sentence performs or receives the action.

Consider the following example: "The watchman opens the door." In this active voice sentence, the watchman (subject) acts as opening the door.  

In passive voice, the sentence becomes "The door is opened by the watchman," where the focus shifts to the door (object) receiving the action.

Guidelines for Converting Active to Passive Voice: 

Rule #1: Identify (S+V+O) Components

  • Active: He drives a car. (Subject: He, Verb: Drives, Object: Car) 

Rule #2: Interchange Subject and Object

  • Passive: The car is driven by him. (Object "car" is exchanged with the subject "He"). 

Rule #3: Subject Omission in Passive Voice

  • Passive: Milk is sold in liters. (Subject omitted when its presence is unnecessary for meaning). 

Rule #4: Change to Past Participle

  • Active: She prepares dinner. 
  • Passive: Dinner is prepared by her. (The base verb "prepares" changed to past participle "prepared"). 

Rule #5: Pronoun Transformation

Active Voice Pronoun  

 Passive Voice Pronoun 

I 

Me 

we 

Us 

She 

Her 

You 

You 

He 

Him 

they 

Them 

  • Active: I write a letter. 
  • Passive: A letter is written by me. (Pronoun "I" changed to "me" in passive voice). 

By adhering to these rules, one can seamlessly transform sentences from active to passive voice, adapting pronouns and structures for effective communication. 

Rule #6: Employ the appropriate auxiliary Verb (is/am/are/was, etc.). The usage of auxiliary verbs in passive voice sentences varies based on the tense, and distinct rules apply to each.

    Example: The hero rescued the hostages 
  • Passive Voice: Intermittently employed to create suspense or shift focus.
